Powder spray and oil spray coating materials:
Powder spraying: Powder spraying uses solid powder coatings, usually composed of resins, pigments and other additives. These powder pigments do not need to be diluted or evaporated before painting because they are solid.
Oil spraying: Oil spraying uses liquid paint that usually needs to be diluted to the proper viscosity before application. Liquid paint usually consists of organic solvents and pigments.
